Social Anxiety: Symptoms, Causes, Diagnosis and Treatment

Social anxiety disorder is a mental health condition characterized by intense and persistent fear or anxiety in social situations because of concerns about being judged, rejected or embarrassed. It can affect relationships, education, work and everyday activities, but evidence-based treatments can help manage symptoms.

Key Takeaways

• Social anxiety disorder involves persistent fear or anxiety about social or performance situations and possible negative evaluation by others.
• Symptoms can include blushing, sweating, trembling, rapid heartbeat, nausea, difficulty speaking and avoidance of social situations.
• Social anxiety is different from ordinary shyness when the fear and avoidance significantly interfere with everyday life.
• The exact cause is not fully established; biological, genetic and environmental factors may contribute.
• Cognitive behavioral therapy (CBT) is a well-established treatment, while certain medications may also be considered following professional assessment.

What Is Social Anxiety Disorder?

Social anxiety disorder, also called social phobia, causes intense fear or anxiety in situations where a person may be observed, evaluated or judged by other people. Common situations include meeting new people, speaking in front of a group, eating in public, making phone calls, dating or asking for help in public places.

People with social anxiety may worry that they will say or do something embarrassing, appear anxious or be negatively judged. The anxiety can occur before an event, during the situation and sometimes afterward when the person repeatedly thinks about how they behaved.

Clinical Insight

Research suggests that cognitive behavioral therapy (CBT) is an effective treatment for social anxiety disorder. A systematic review and network meta-analysis of 101 clinical trials involving 13,164 participants found that individual CBT significantly reduced social anxiety symptoms compared with waiting-list controls.

Social Anxiety vs. Shyness

Being shy in unfamiliar situations is common and does not necessarily indicate a mental health disorder. Social anxiety disorder is more persistent and can cause substantial avoidance or distress that interferes with everyday activities, relationships, education or work.

What Causes Social Anxiety?

There is no single confirmed cause of social anxiety disorder. Current evidence suggests that biological, genetic and environmental factors may all contribute. Negative social experiences and stressful or adverse experiences may also play a role in some people.

Research has also examined the relationship between social anxiety and other psychological conditions. Social anxiety disorder can occur alongside mood and other anxiety disorders, and identifying coexisting conditions can be important when evaluating symptoms and treatment needs.

Having a particular risk factor does not mean that someone will develop social anxiety disorder. The condition appears to result from a combination of factors rather than one specific cause.

What Are the Symptoms of Social Anxiety?

Social anxiety symptoms can involve emotional, behavioral and physical reactions. The intensity may vary depending on the situation and the individual's concerns about being evaluated by others.

Emotional and behavioral symptoms may include:

• Intense fear of being judged, rejected or humiliated
• Excessive worry before social situations
• Avoiding conversations, meetings or social gatherings
• Difficulty speaking or maintaining eye contact
• Fear of eating, drinking or performing in front of others
• Constantly thinking about how one appeared to other people
• Avoiding situations where attention may be focused on them

Physical symptoms can include:

• Blushing
• Sweating
• Trembling
• Rapid heartbeat or palpitations
• Dizziness
• Nausea or stomach discomfort
• Difficulty speaking
• Feeling faint or overwhelmed

When symptoms become persistent, they may contribute to difficulties at school or work, relationship problems and reduced quality of life.

How Is Social Anxiety Diagnosed?

There is no blood test or imaging study that independently confirms social anxiety disorder. Diagnosis is based primarily on a clinical assessment of symptoms, their duration, avoidance patterns and their effect on daily functioning.

A healthcare professional may assess:

1. Social situations: Which situations trigger anxiety or fear?
2. Thoughts and concerns: Is there a persistent fear of negative evaluation?
3. Avoidance: Are social situations avoided or endured with intense distress?
4. Physical symptoms: Are symptoms such as sweating, trembling or palpitations present?
5. Duration: Have the symptoms persisted for at least six months?
6. Daily impact: Do symptoms interfere with work, education, relationships or other activities?
7. Other conditions: Could another medical, psychological or substance-related factor better explain the symptoms?

Clinicians may also use structured questionnaires or rating scales to assess symptom severity. Research has described tools such as the Liebowitz Social Anxiety Scale and Social Phobia Inventory for evaluating different aspects of social anxiety.

How Is Social Anxiety Treated?

Social anxiety treatment generally focuses on reducing anxiety and avoidance while improving the person's ability to participate in everyday social situations. Treatment is individualized according to symptom severity, coexisting conditions and personal circumstances.

1. Cognitive Behavioral Therapy

Cognitive behavioral therapy (CBT) is a well-established psychological treatment for social anxiety disorder. It focuses on identifying unhelpful thought patterns and behaviors and developing more adaptive responses to social situations. CBT for social anxiety commonly incorporates exposure to feared situations.

Evidence-based guidelines recommend CBT specifically developed for social anxiety disorder as an important psychological treatment option.

2. Exposure-Based Therapy

Exposure involves gradually confronting situations that cause anxiety within a structured therapeutic approach. The purpose is to reduce avoidance and help the person learn to manage anxiety in situations they previously found difficult.

Exposure may be incorporated into CBT rather than performed as an uncontrolled or overwhelming exercise.

3. Medication

Medication may also be considered for social anxiety disorder. Evidence-based guidelines support the use of certain selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) for adults with social anxiety disorder.

Medication choice should be determined by a healthcare professional after considering symptoms, other medications, medical history and potential adverse effects.

4. Combined Approaches

Depending on the clinical situation, psychotherapy and medication may be used separately or together. The appropriate approach depends on the individual's symptoms, preferences and treatment response.

What Are the Benefits and Possible Risks of Treatment?

Effective treatment can help reduce social anxiety symptoms, avoidance and functional impairment. Research indicates that CBT can produce improvements that persist beyond the active treatment period, although individual responses vary.

Psychotherapy generally does not carry the same medication-related adverse effects, but discussing uncomfortable situations during treatment can temporarily increase anxiety. Medication can also cause side effects, and the potential benefits and risks vary according to the medication used.

Treatment therefore requires ongoing clinical assessment, particularly when symptoms are severe or when other mental health conditions are also present.

What Is the Recovery and Follow-Up Process?

Social anxiety disorder can be persistent without treatment, and symptoms may continue to interfere with daily functioning. With appropriate treatment, however, symptoms can be managed and quality of life may improve.

Follow-up may focus on changes in anxiety, avoidance, physical symptoms and participation in everyday activities. Treatment may be adjusted according to progress, side effects and the presence of other conditions.

When Should You See a Doctor?

Consider seeking professional assessment when social anxiety becomes persistent, causes significant distress or interferes with everyday activities.

Professional support may be particularly appropriate when:

• Social situations are consistently avoided
• Fear of judgment interferes with work or education
• Anxiety makes it difficult to maintain relationships
• Physical symptoms are severe or frequent
• Anxiety prevents participation in ordinary activities
• Symptoms are accompanied by depression or other significant psychological difficulties

Social anxiety itself is not usually a medical emergency. However, severe psychological distress or thoughts of self-harm require immediate professional attention.
